This conduit 32 is U-shaped vide an improved shoe finishing machineby and is secured to the casing by screws 33. The 5 means of which thesole or other part of the shoe conduit 32 passes through the slot I2 andter- 5 may be properly finished and wherein novel minates in a segmentalhousing 34 which is dismeans is provided for removing the material posedadjacent the abrasive member 21.
